Overview of Feasibility

   

Operational Feasibility

 A proposed system will be used effectively after it has been developed

Technical Feasibility

 Refers to the technical resources needed

Economic Feasibility

 Benefits vs. costs

Schedule Feasibility

 Means that a project can be implemented in an acceptable time frame 8 8

Preliminary Investigation Overview

 Planning the Preliminary Investigation  A systems analyst typically follows a series of steps  The exact procedure depends on the nature of the request, the size of the project and the degree of urgency 9 9
